CONDENSER FOR STEAM-PUMPS.

SPECIFICATION forming part of Letters Patent No. 272,456, dated February 20, 1883.

- Application filed December 28, 1882. (No model.)

To all whom it may concern:

(.lopake Iron Works, in the county of Oolum-' bia and State of New York, have invented an 1m provement in Condensers for Steam-Pumps, of which the following is a specification.

I make use of a series of steaniways placed transversely to the suction water-way of the pump and admit the steam from the exhauststeam pipe into such transverse steam ways, so that the steam passes into the water from a numberofnarrow spaces and is condensed with rapidity. I combine with the steamways, exhaust-steam pipe, and water-way a'check valve or "alves that prevent the water passing into the steam-pipe, as the steam may condense more rapidly. than it is supplied, especially when theengine is running slowly.

In the drawings, Figure 1 is a section of the suction waterway and steam-pipe, longitudinally of the latter. Fig. 2 is a section at the line w m. Fig. 3 is a section of a modification of the steamway. Y

The pipe a leads to the Water-supply, and the pipe b to the pump. The pipe 01 conveys the exhaust-steam into the water-way. At the junction of these pipes I provide a chamber, a, which by preference is flattened in one direction and extended in the other direction, so as not to interfere with the free flow of water in the suction water-way; and at the same time allow for the introduction of elongated steam passage-ways i, that extend across the water-way, and are a continuation of or in line with the exhaust-steam pipe d, so that as the steam issues from the pipe (I it will spread it self along in these steam-waysi, and pass gradually into the water and be condensed. 1f the pipes at b are horizontal, the steam waysz'should be in the upper part of the chamber a. If the pipes at b are vertical, the partitions 0 between one steam'wayt' and the next may be inclined downwardly, as in Fig. 2, to give better opportunity for the steam to pass along below the inclined partition.

I generally prefer to make the steamways in the form shown in Fig.3, wherein there are valves or deflecting-lips l, or sheet metal or other suitable material, attached to the flat surfaces formed at the edges of the partitions,

' so that these deflect the water as it passes by the openings between the edges of the lip l and' th'e ends of the partitionso. If these deflecting-lips are suffioiently flexible, they will close down against the ends of the partitions o and form valves, it the vacuumin the steaming-lips will render the use of other or check valves unnecessary.

I have shown a check-valve", r, in the exhaust-steam pipe d, which check-valve opens to the steam as it flows toward the water-way; but this valve closes whenever the steam condenses in the pipe 01 and the vacuum becomes greater than that in the suction water-way. Thisi prevents the water flowing into the exhaust-steam pipe.

I claim as my invention- 1. The combination, with the suction waterway and the exhaust-steam pipe,of stea'mways passing 'across the water-ways, substantially as set forth. I

a 2. The combination, with the water-way in a steam-pumping apparatus, of the partitions 0, intermediate steamways, and the deflecting-lips l, and exhaust-steam pipe 61, substan- .tially as set forth.

3. The combination, with the suction waterway and exhaust-steam pipe, of steamways passing across the suction water-way and openiug into the water-space, and a check valve or valves, substantially as set forth.
